- The eps_growth_yoy read was never computed, leaving that fixed by_key entry null even with sufficient EPS history; now growth_read() is applied to EPS history just like revenue. - Tests: same-day earnings returns as next with days_until 0 (and not in recent); zero close guards valuation to null; eps read populated. Fixture seeds three fiscal years so YoY growth reads have a >=3 run. 9 API tests pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
